Polar stratospheric clouds facilitate the formation of

Polar stratospheric clouds facilitate the formation of

Options

  1. AClONO2{ClONO}_{2}
  2. BHOClHOCl
  3. CClOClO
  4. DCH4{CH}_{4}

Correct answer

B. HOClHOCl

Step-by-step solution

Polar stratospheric clouds surface act on catalyst which provided surface on which hydrolysis of ClONO2{ClONO}_{2} takes place to form HOClHOCl (Hypochlorous acid)

ClONO2(g)+H2O(g)→HOCl(g)+HNO3(g){ClONO}_{2}\left(g\right) + {H}_{2}O\left(g\right) \to HOCl\left(g\right) + {HNO}_{3}\left(g\right)

Polar stratospheric clouds (PSCs) play a central role in the formation of the ozone hole in the Antarctic and Arctic.
